Since the beginning of the month, 6 dozen earthquakes have struck in and around Los Angeles California, with several of these events being felt by nearby residents. Two clusters of these earthquakes are occurring near North Hollywood and Malibu in response to a magnitude 3.8 and 4.1 mainshock respectively. Today's video will discuss why these earthquakes occurred, what faults caused them, and the average rate of similar magnitude earthquake within the Los Angeles Metropolitan Area.
